Desert Technology: Modules Made for Extremes

Standard panels are made for regions with a moderate climate. All promises for performance and durability are based on moderate weather conditions; such as those found in Germany.
 
Many research companies (e. g. IRESEN in Morocco) have conducted extensive tests with standard panels in desert regions or in regions with temperature higher than those found in central Europe: Most panels lose much of their nominal power after 10 years and only some of panels continue to work for more than 15 years at 80% capacity.

J. v. G. Thoma GmbH has been working on a special technology for very rough climates for more than 7 years.

Jurawatt now produces and sells these special DESERT panels all over the world. Facts about the new DESERT panels from Jurawatt can be found here.

Better Performance & More Power when it's hot

The hotter the cell is, the less power comes from the panel. Because we know that every watt counts, we have developed a combination module and cell that will generate more wattage at the same nominal power.
 
Normal PV panels have a temperature coefficient of about -0.45%/ per calorie. Our specially optimized cells improve this coefficient by roughly 15%, which leads to improved power generation. The power benefit will increase with each degree of heat.
Desert Performance

30% More Earnings & Long Life even in Hot Areas

A damp heat test is part of simulating how a panel ages. This damp heat test increases the temperature to 85% in combination with a humidity of 85%. Doing this will age panels faster and simulate 20 years time when the test is performed over 1,000 hours.
 
If the normal temperature of the cell in hot areas will be 50-70 degree then such tests will not simulate 20 years, but rather 10-15 years maybe, because panels in hot areas will age much faster than in Germany.
 
Our panel can easily survive 2,000 hours in a damp heat test without any problems. This means that, even in desert regions, we can guarantee lifetimes of 20 years or more.
 
For example, if the panel will work 30% longer than a normally processed panel, a huge financial advantage will be created, one that is much greater than the few cents per watt, which the technology might cost the end consumer.

Works where other Panels fail

Not only is the power benefit and the longer lifetime a major advantage of Desert Technology, but also the fact that these panels can be used in regions where other panels simply will not work.
 
The data sheets for most panels available on the market indicate a maximum temperature of 85°C - 90°C. This means that if the panel will be operating in temperatures greater than 90°C, it will be out of spec and using it in areas where such temperatures can be expected will not be possible, OR the performance warranty will immediately be invalidated.
 
Even in Germany on hot days, cells can achieve temperatures over 80°C.
 
These desert panels can take temperatures up to 125°C.
